Ecto SQL (documentation) provides building blocks for writing SQL adapters for Ecto. It features:
- The Ecto.Adapters.SQL module as an entry point for all SQL-based adapters
- Default implementations for Postgres (Ecto.Adapters.Postgres), MySQL (Ecto.Adapters.MyXQL), and MSSQL (Ecto.Adapters.Tds)
- A test sandbox (Ecto.Adapters.SQL.Sandbox) that concurrently runs database tests inside transactions
- Support for database migrations via Mix tasks
To learn more about getting started, see the Ecto repository.
Clone the repo and fetch its dependencies:
$ git clone https://github.com/elixir-ecto/ecto_sql.git
$ cd ecto_sql
$ mix deps.get
$ mix test.all
Note that mix test.all runs the tests in test/ and the integration_tests for each adapter: pg, myxql and tds.
You can also use a local Ecto checkout if desired:
$ ECTO_PATH=../ecto mix test.all
You can run tests against a specific Ecto adapter by using the ECTO_ADAPTER environment variable:
$ ECTO_ADAPTER=pg mix test
MySQL and PostgreSQL can be installed directly on most systems. For MSSQL, you may need to run it as a Docker image:
docker run -d -p 1433:1433 --name mssql -e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD=some!Password' mcr.microsoft.com/mssql/server:2017-latest
It is also possible to run the integration tests under a containerized environment using earthly:
$ earthly -P +all
You can also use this to interactively debug any failing integration tests using the corresponding commands:
$ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang-20.3.8.26-alpine-3.11.6 --build-arg MYSQL=5.7 +integration-test-mysql
$ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang-20.3.8.26-alpine-3.11.6 --build-arg MSSQL=2019 +integration-test-mssql
$ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang-20.3.8.26-alpine-3.11.6 --build-arg POSTGRES=11.11 +integration-test-postgres
Then once you enter the containerized shell, you can inspect the underlying databases with the respective commands:
PGPASSWORD=postgres psql -h 127.0.0.1 -U postgres -d postgres ecto_test
MYSQL_PASSWORD=root mysql -h 127.0.0.1 -uroot -proot ecto_test
sqlcmd -U sa -P 'some!Password'
